The study says, however, that New Zealand companies are ahead of the rest of the world in encouraging female employees to pursue leadership positions, and Parkes says she is aware of activities and initiatives that offer gender-specific encouragement to women such as mentoring, networking and general sharing of experiences.
"Women do this naturally, so the creation of forums and opportunities to do this are what is needed, given we have such busy agendas regardless of our home life situation."
Professor Sarah Leberman runs the Achieving Career Excellence programme at Massey University, where top female students are supported in their transition into the workplace by being exposed to different female leaders and understanding their journey to the top.
She says often female graduates are not confident at communicating, will take the first job offered and are not good at negotiating.
Parkes, a former guest speaker to the programme, says: "This helps them understand how to promote themselves, how to achieve their goals and how to get what they want without compromising their life choices."
Leberman says the five-week programme, which covers leadership, career planning, negotiating, communicating and "where to from here?" has been well received by students and found valuable by those now in the workplace. The programme is being run at all three Massey campuses, and similar courses are now being picked up by other universities.
Parkes thinks it is debatable whether businesses should be actively promoting women into leadership roles as she believes a greater level of diversity is what is required.
Paul Robinson, New Zealand director of recruitment for HR specialists Randstad, agrees. He says the key is for business leaders to recognise, develop and reward the best person for the leadership role every time.
Parkes says, however, that having a greater level of gender diversity at the management, leadership and boardroom table level is a useful dynamic as it is different.
"I think that women bring a different perspective to the table - one that often demonstrates a wider sense of business, a more holistic approach. Their perspective comes from a different attitude, different life experiences and a different lens than men have, however, this is of course true of every person."
Perceptions over the impact flexible and part-time working arrangements can have on career opportunities are mixed, with 47 per cent of New Zealanders surveyed believing part-time work hinders career progression.
Parkes says it is difficult to generalise how employers can assist women in balancing a leadership position with home and family life.
She says there needs to be an individual approach to those women identified with the potential to hold a leadership role, but a focus on outcomes rather than input would be one way of encouraging women to engage in more senior roles.
"Being driven more by deadlines and outcomes, and encouraging more virtual management and less office-bound or geographically bound roles is what is needed," Parkes says.
"A woman can re-engage with work later in the evening once her family responsibilities are complete but leave earlier in the afternoon so she can meet those demands."
